Setting Parameters

Before moving forward, you need to make sure some of the parameters are setup properly before connecting the spindle. Failure to do so could burn up your spindle.

How to Edit a Parameter

To edit one or more parameters, start by hitting the SET button. You will be presented with a Pn xx display like the one shown here.

You change the actual parameter number you want to edit by using the up/down arrows. Here I changed the parameter number to Pn 02.

Note that you can use the JOG buttons to move the digit you will be affecting with the arrow keys.

To edit a parameter hit the SET button. You will be presented with the value of the parameter you selected. In this case, parameter Pn 02 has a value of 400.00 as shown here.

To change the value, use the up/downarrows. Remember you can use the JOG buttons to change the digit you want to edit.

To apply the new value, hit the SET button again. The new value will be saved and you will be taken to the next parameter. In this case, we moved to parameter Pn 03.

Initial VFD Parameters for the MASSO

Pn 01=24000

Pn 02=400

Pn 03=4

Pn 04=2

Pn 05=3

Pn 12=400

Wiring the MASSO to the VFD

Make the following connections between the MASSO and the VFD.

MASSO Spindle 1 to VFD 10V IN

MASSO Spindle 4 to MASSO Spindle 6

MASSO Spindle 4 to VFD GND

MASSO Spindle 5 to VFD FWD

MASSO Spindle 7 to VFD REV

In addition you need to wire the VFD GND terminal to your Ground terminal block.

Configuring the MASSO

Configuring the MASSO is pretty easy. Just bring up the Spindle form and make sure VFD is selected. Set the spindle speed at 10 colts field to 24000. You can tweak this a little by adding or removing a little from the setting.

Add to the setting to lower the speed a little. Subtract from the setting to raise the speed.

Testing the VFD

Bring up the MDI Command form and type in S5000 and hit enter. This sets the speed you want the VFD to run.

Then type in M3 and hit enter. This starts the spindle.

Your spindle shout start and be running ClockWise (as looking down from the cable end of the spindle).

Reversing the Spindle

When you start the spindle with the M3 command, if the spindle is not rotating in the clockwise direction, you will need to reverse two of the leads on the spindle cable as shown here.

This is what happens when the spindle rotation is reveresed.
